An interesting use of Geotags

Here's an interesting use of Flickr data. Thanks to ASC for pointing it out.

"We retrieved from Flickr, large amounts of photo taken by thousands of users in the world’s most photographed cities. Based on the time, explicit location and people’s description of their photos, we design geovisualizations. They reveal patterns of tourists and citizens consuming a city, such as the flow of people between city attractions (see figures below), the monuments areas of influence or what is happening with day/night and working/weekend periodicity."
